in reply to Problems with HMAC SHA-256

The documentation is pretty clear about how to calculate using the hmac algorithms: 

#!/usr/bin/perl
use warnings;
use strict;

use Digest::SHA qw(hmac_sha256_hex);

my $digest=hmac_sha256_hex("138539083512345apiKeyDEMO","apiSecretDEMO"
+);
print "Digest=$digest\n";

Update: output:

Digest=696e087f4b1902aa58d35e75b4600580d70a92ed68b23379373117fb3fe3064

    Thanks very much to everyone for the prompt replies. You are of course correct, I should have used hmac_sha256_hex instead of just sha256_hex if I want to include my own encryption key as the last argument. Otherwise, as pointed out, it just combines all the arguments into one string and then uses its own key.

    Thanks once again.
